To all-'whomvit may concern.'

Be it known that I, DANEL W. SHIEK,

a citizen of the'United States', residing at" .'Indianapolis, in thecounty of Marion and State of Indiana, vhave invented certain new anduseful Improvements in Calculating and Listing Machines, of which thefollowing is a description.

lMy invention relates to that class of devices known' as adding orcomputing machines wherein computations'may be accurately performedmechanically by the manipulation of the'proper keys or levers of themachine, and o/ne wherein the operation of listing may also beperformed, that is, a permanent record of the keys manipulated may beproducedby the machine so that if desired the several operations may bechecked to insure their accuracy.

The object of my invention is to produce a-,machine that will' beabsolutely accurate and exact in its operation and which may be easilyand readily controlledto perform its various` functions, and one whichwill'be simple,l durable'and compact and not liable .to accidental'disarrangement rendering the same wholly or partiallyinoperative orinaccurate. 'I To this end my invention consists inthe novelconstruction, arrangement, and combination of parts herein shown anddescribe'd, and more particularly pointed out in the claims. In theaccompanying drawings, wherein like or similar reference charactersindicate like or corresponding parts; Figure 1 is a sideelevation of Amylmachine arranged for listing with parts removed and broken away to moreclearly showthe construction. Fig.

Fig. 27 is aperspective detail ot' a portion o'f the carrying mechanism. Figs. 28and 29 are details of the total indicator actuating mechanism. Fig. 30isa fragmentary plan view of the indicators and coiiperating parts. Fig.31 is a perspective view of the indicator controlling mechanism and thecoperating parts. Fig. 32 is a partial plan .'icw v of the computingdevice.A showing the. single keyboard employed.- Fig.' 33isaefr'ntrij-le# stantially horizontal guide plate or equivalentA means3, each provided with suitable openings to receive the upper and lowerends respectively of the key shanks or stems 4 upon which thecontrolling keys 5 of my machine are mounted. (Figs. 1, 2, 3 and 4.) Anydesired numberv or arrangement of keys or levers may be provided foroperating my device. As shown the controlling vkeys are arranged in aplurality of series, one. for each numerical order within the capacityof the machine, with a key 6 com# mon to the several .series foroperating the recording mechanism. (Figs. 1 to 4, 22 and 32.) Eachseries of controlling keys consists of a set of nine keys representingthe numerals from 1 to 9 inclusive and a release key 7. (Figs. 1 to 4,26 and 32.) The key stems 4 are preferably square or otherwise suitablyformed to preventI their turning'in the plates 2 and 3 and each stem isprovided with two laterally projecting pins or equivalent means 8 and 9.(Figs. 3 and 4.) A bar 10 is provided for each series of keys rigidlysecured in a substantially horizontal position between the key-` board 2and the guide plate 3 and a substantially triangular plate 11 ispivotally mounted upon the bar 10 for each key in the series. (Figs.1,'3 and 4.)

The plates 11 may be mounted upon the bar V10 in any suitable manner.

As shown each plate is pivotally attached near one of its corners to thebar as at 14 with one face of the I.plate extending substantiallyhorizont/ally a'nd the other face extending downw rd past the key shank4 With which it'is a aptedf "to coperate. A spring 12 or other suitablemeans is provided arranged to tend to rta'tp the plate 11 upon itspivotal support 14 in a direction to depress the free end of .itshorizontal face. A portion of the face 15 of each plate 11 near itsupperend is offset slightly providing a shoulder as at 16 adapted to engagethe pin 9 upon its particular keyshank when the key is in its elevatedposition and support the same. Any downward movement of the key 'whenthus positioned will obvidusly tend to rotate its particular plate 11 ina direction to elevate t e'free end of its horizontal face.

In the form shown a lateral projection 18 is provided at the free end ofthe face 15 of each plate extending substantially at right angles to theplane of the plate. A substantially horizontal bar 19 is provlded havinga .downwardly extending finger 2O for each plate 1l suitably positionedto engage the respective projections 18, and lock the plates a ainstrotation, thereby positively locking al of the keys of the series whoseplates are thus engaged against downward, movement.

" The bar 19 may be attached to the frame 1 or other stationary portionof my device attached atone end to the bar 19 near its opposite endsrespectively and at their opposite ends to the bar 10. The distancebetween the pivotal connections of the links to the bars 10 and 19 aresubstantially the same so that the bar 19 will be free to move upwardand longitudinally yet` remaining practicallyfparallel to its normalposition. The fingers 20 are preferably inclined to substantiallycorrespond with the direction of movement of the bar.

Any suitable means may be provided to control the movements andpositions of the bar 19. In the. form shown' a pair of Ibell cranklevers 23-24 and 25-26`are rotatably' mounted upon the fixed shaftsv 27and 28 respectively. A bar 29 is pivotally attached to, and connects,the free ends of the arms 23 and 25, and the parts are so proportionedand arranged that the bar 29 will at all times remain substantiallyparallel to-its normal position. The free ends of the arms 24 and 26 arealso preferably pivotally connected by rod or bar 30 so as to insure theregular an `uniform parallel movement of the bar 29 as it passes thepivotal supports 27 and 28 of the bell cranks.

A spring 31 or other suitable means extends rom the bar 30 to a suitableportion of the frame 1 of my machine adapted. to normally maintain thebar 29 in itselevated position. An arm 32 is rigidly att-ached to thebar 19 and provided with a horizontal projection 33 near its upper endarranged to extend into the, path of the bar 29 to move the bar 19vertically upon a sullicient vertical movement of the bar 29. The pins 8upon the key Shanks 4 are arranged directly above and engaging the bar29 so that the downward movement of any key in a series will carry thebar 29 of that series downward and permit of a similar movement of thebar 19. This movement of the bar 19 causes the lingers 20 to engage theparts 13 of the several plates 11, except of the particular plate`11cooperating with the shank 4 whose movement is temporarily .controllingthe position of the bar 29, and lock all the keysnot so depressed intheir normal' elevated position. The initial movement of the keytemporarily controlling the parts, in its initial movement rotates itsparticular plate 11 suiiciently to carry its part 18 past the finger 2Oadapted to coperate'the'rewith. The several keys and their coperatinglocking parts remain -in the positions above described until the keyoperated has completed its stroke and is returning to its normalposition, when the part 33 of the bar is engaged by the bar 29 andelevates the bar 19 releasing all of the keys of the of a key, until thestroke is completed. As shown a segment 34 is pivotally mountedupon asuitable stationary portion of my device as at 35 and connected'to thearm 23 of the bell cranks 2324 or other' suitable movable portion of'the machine by a link 36 or .equivalent means so that the movementofthe segment 34 Will correspond Withl the movements of any key in aseries'. A double acting p'awl 37is provided pivotally mounted as at'38upon a suitably fixed portion ofthe frame and arranged to engage thecurved face of the segment 34 when the same is moved, in eitherdirection' to prevent its reverse movement until the segment Y. hasreached the limit oitsmovement. The

`lengt-h of the segment is such thatwhen' key reaches the limit of itsdownward movei nient thepawl passes beyond the end `offthe segment, andengages'the'segment in the o'ppositie direction whileI it is returningand prevents af second depression of the key until the keyfis fullyrestored to its normal position,` whenthe pawl passes from thefop.-

posite end ofthe zsegmen't'freeing themec anism. Any suitable -means'maybe providedy to' esiliently -hold the pawl 37 in position to engage theface' of the segment when moving-in either direction. In the form shownan arml 39 is pivotaflly mounted as at 40, a lateral pin or projection41 is provided upon the pavvl 37 and a V-'shaped notch or depression 42-isl provided inthe arm 39 adapted to engage the projection 41 and tendto resiliently hold the pawl 37 in a radial position to Athe segment 34.A spring 43 or other suitable means, is pro. vided tojresiliently forcethe inclined vfaces of the depression 42 against the'pin-as above:

described., Suitable means are preferablyA provided (tof force the paivl37 out ofJ enx shown in Figs. 1G and 17.l has the lower end gagemenijWith the segment 34 when it is desired to release a key before thesa'mehas completed ,its stroke. For this purpose, m the vform shown, theshank of the release key 7` is provided with a lateral projection 43 adaAted to engage the pawl 37 to hold the sameout of engagement with thesegment. Ally suitable means may be yprovided for controlling theoperation of my device by the movement or position of the keys 5 5. Asshovmla horizontally movable bar 44 is provided for each series of keyspreferably positioned substantially in the plane. of, and directlyabove, .the plates 11 for that particular series. The bar 44 is providedwith`a plurality of shoulders or stops/15 upon its loweredge'-correspondi'1ig 'to the sired manner;

.v'ide'd for each series. of' ,fkeys pivotally `mounted nearrone. endupon the shaft 28 4and connected by a link `49 or equivalent `controlledby the bar 44.

The several stops 45 are so positioned inrelation to the plates 11 as to permit, for each successive key in aseries; a\regular .gradual increase in the allowed travel of the bar 44from the shortest to the longest distance, the amount in each case beingregulated by the position in theseries of the particular key operated.That is to say, the distance traveled by the bar in each case dependsupon the particular key operated and is regularly increased from thefirst or one key to the last or ninth key inclusive/ v As shown the bar44 is supported upon the frame lby suitable pins 4G46 rigidly securedup'on the frame and loosely positioned in slots 47 in the opposite endsof the bar formed to permit the desired movement. The indicating andcomputing mechanism may be'controlled by the bars 44 in any de- As showna lever 48 is promeans to vthe bar 44 of itsjparticular series.

,A lever 50 Vis also provided for each series pivotally'mounted upon theshaft 28 and 'arranged to coperate with the bell crank 25-26 and lever48, so that the movements of the bell crank Will lie-.communicated tothe levers'48 and 50. The extent of the movement of both of the le'versis preferably (Figs. 3 and 4.), Any suitable means mav be provided forthis purpose. As shown, Figs. 13 to 18 inclusive, the bell crank 25-26is provided with a cylindrical boss 51 concentric with :the shaft y28,and the lever 50 is provided with an opening nea-r one end a part ofwhich is adapted to fit the boss and with a part extendinf.Ylongitudinally of thelever `as at 52 to receive a. spring actuatedtongue 53. This tongue or dog 53 in the preferred form loose-ly butpivotally seated in a'proper recess formed in the yoke 50. The free endof thetongue 53 is resiliently pressed against the circumference .of theboss to operate as a. clutch to frictionally engage the same to move'tnelever With the bell crank in one direction, and leave the partssubstantially free from each other when the bell crank moves in theopposite direction. The lever 48 is preferably providedwith a pin 54 orequivalent means extending into the openingr 52 in position io enga:vith the tongue 53 whereby the lever. 48 is prevented from moving Awiththe lever 50 during the downward movement of a key. A pin 55 orequivalent 'means is also provided upon the bell crank
